Abstract
The invention discloses a device used in a matching way during the overhaul of a high-voltage shunt capacitor of a transformer station, in particular relates to a grounding device dedicated for a high-voltage shunt capacitor of a transformer station. The grounding device mainly comprises a grounding pile base, and a grounding pile body arranged on the grounding pile base, and has the structural characteristics that transitional nuts are symmetrically arranged on two sides of the grounding pile body, and a wing-shaped nut and a grounding-wire joint bolt are respectively arranged outside the transitional nuts. The device disclosed by the invention has the advantages of safety in use and high working efficiency.
Description
Technical field
Matching used device when the present invention relates to the high-voltage parallel capacitor maintenance of a kind of transformer station, the special-purpose earthing device of specifically a kind of transformer station high-voltage parallel capacitor.
Background technology
When transformer station's high-voltage parallel capacitor appearance damage is changed, in order to prevent misdelivery electricity or other and capacitor associated devices the counter safety of sending electricity to jeopardize the field personnel in maintenance process, to occur, need at capacitor group low-pressure side installing earth connection to capacitor.Because capacitor does not have special-purpose grounding wire device, so earth connection can only be connected on the ground connection band iron by the wire clamp that twines or install additional.Have the following disadvantages: the one, connect unstable potential safety hazard; The 2nd, also need to remove the corrosion resistant coating on the ground connection band iron during installing, recover the corrosion resistant coating on the ground connection band iron after connecting again; The 3rd, the ground connection band iron is close to the capacitor tower base, can be very little for the position that mounts earth connection, and the set-up time is longer.
Summary of the invention
Task of the present invention provides the special-purpose earthing device of transformer station's high-voltage parallel capacitor of a kind of safety, high efficiency.
For realizing above-mentioned task, technical solution of the present invention is:
The special-purpose earthing device of a kind of transformer station high-voltage parallel capacitor, mainly the ground stud body by ground stud base and upward setting thereof constitutes, its design feature is in ground stud body bilateral symmetry transition nuts to be set, and aerofoil profile nut and earth connection track bolt are set respectively outside transition nuts.
The present invention has safe in utilization, the advantage of high efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the special-purpose earthing device of a kind of transformer station high-voltage parallel capacitor, mainly by ground stud base 1 and go up welding ground stud body 2 constitute, bilateral symmetry at ground stud body 2 is installed transition nuts 4, in the outside of transition nuts 4 aerofoil profile nut 3 and earth connection track bolt 5 is installed respectively.
During use,, only need earth connection 6 is inserted in the ground stud body 2 by earth connection track bolt 5, fix, carry out fastening getting final product by aerofoil profile nut 3 again by transition nuts 4 owing to weld on ground stud base and the ground connection band iron.When removing earth connection 6, dismounting aerofoil profile nut 3 is removed transition nuts 4 more earlier, earth connection 6 is extracted from ground stud body 2 by earth connection track bolt 5 to get final product again.
Claims (1)
1. special-purpose earthing device of transformer station high-voltage parallel capacitor, comprise the ground stud base and go up the ground stud body that is provided with, it is characterized in that: in ground stud body bilateral symmetry transition nuts is set, aerofoil profile nut and earth connection track bolt are set respectively outside transition nuts.
